Abstract :
This paper presents a novel downhole power supply control system using fuzzy PID control strategy. The control system is powered by a downhole turbine generator which generates AC voltage. The output of the turbine generator is processed through a full wave bridge rectifier and filter, and then input to the phase-shifted full-bridge PWM controller. A digital signal processor TMS320F2809 is used as the main control unit of the regulator control module. In order to verify the effectiveness of this system, a fuzzy proportion integration differentiation (F-PID) controller is used to control the phase-shifted full-bridge switching power supply, and the results presented that the controller can ensure the stability for power supply.
